Adidas Adizero SL Review: A Lightweight Trainer That Gives You a Break From Super Shoes

Introduction

Some shoes try to do everything at once, and others know exactly what they are. The Adidas Adizero SL sits firmly in the second camp. It is a true definition of a lightweight trainer: a shoe that can handle daily training for some runners and take on faster workout duty for others. It is not a super shoe, so you get a bit of a break from that category, but it still carries elements that make it feel a little quicker than an ordinary trainer.

That balance is precisely why it deserves a closer look.

What the Adizero SL Is

In its category, the Adizero SL is the kind of shoe that earns its place in a rotation rather than replacing everything in it. It is designed to be a genuine lightweight trainer, capable of daily miles for some runners and up-tempo sessions for others, without the aggressive geometry and max foam of a modern super shoe.

The specs have been a little vague across sources. Weight has been reported at around 8.6 ounces, with Adidas listing 8.5 ounces, and women’s sizing consistently comes in around 7.4 ounces for a women’s size 8. Stack heights are similarly approximate: roughly 35/25 mm in the heel and forefoot for men, and about 33/25.5 mm for women. The effective drop feels closer to 8 mm, though that is splitting hairs slightly.

Ride, Foam, and Traction

Underfoot, the Adizero SL uses full-length Lightstrike with some Lightstrike Pro in the forefoot. The ride is slightly firmer than you might expect, and the Lightstrike Pro feels quite firm initially until it breaks in. After around 40 miles of testing, the midsole finally softened up and settled into a more comfortable character.

There are no rods or plates here. It is an unplated, non-super-foam shoe, but it still sits on the stiffer side, especially given the stack height and the light dose of Lightstrike Pro in the forefoot. That stiffness is part of what keeps it feeling snappy rather than soft and sleepy.

Traction is a genuine strength. The grip on the outsole is really good, and it has been used on both trail and road without issue. Durability has held up well over 40 miles, with just a teeny bit of wear and nothing concerning. As with most lightweight trainers, you will get a decent number of miles out of it, though not the highest mileage count in a broader rotation.

Upper and Fit

The upper is a newer, more comfortable design with a wider fit that runs low in volume. If you want some toe room while still getting plenty of security sitting down over your midfoot, this combination works really well. Runners with high-volume feet may not find it as accommodating.

Other fit details include a flexible upper, a non-gusseted tongue, and a flexible heel counter that did not cause any irritation during testing. The overall description is simple: slightly on the wider side, but lower in volume, with some interesting colorways to choose from.

Daily Training and Workouts

Cushioning is plenty for daily use, though it sits on the firmer end of the spectrum. That makes it work really well for runners who prefer a slightly firmer shoe for daily training on roads and light trail, rather than those chasing a plush, soft ride.

It is still snappy enough for faster work. Long repeats, a tempo run, and intervals have all gone fine in this shoe. It is not the fastest shoe available, but it is a great option that gives you a break from super shoes while remaining legitimately quick underfoot.

Who Should Buy the Adizero SL

The most interesting argument for this shoe is about rotation strategy rather than any single feature. Training in super shoes all the time may not be the best thing for your body: runners adapt, legs can stiffen up for softer shoes, and those aggressive platforms tend to put more stress on certain parts of the body. Having a variety of shoes in the rotation is key.

That is exactly where the Adizero SL fits. It is still a reasonably quick shoe, but it gives you a break from super shoes so you can save those for key workouts. If you want a daily trainer you can also use for workouts that are not as aggressive as a super shoe, this is probably a really good option for you.

Conclusion

The Adidas Adizero SL is a well-rounded lightweight trainer with a firm-but-snappy ride, strong traction, good durability for its class, and a wider, low-volume fit. It will not replace a super shoe on race day, and it is not trying to. Instead, it earns its spot as the shoe that keeps your legs fresher, handles daily miles and tempo work, and lets your super shoes do what they do best when it really counts.
